WHY THE MgO MELTING TEMPRATURE IS HIGHER THAN Al2O3 IN SPITE OF AL2O3 MORE COVALENTLY?

Answers

Answered by raskarsantosh240

Answer:

Now the intermolecular bonds (that is bonds between one Al2O3 and another Al2O3) are in fact weaker than the bonds between two magnesium oxide molecules. This results in the greater melting point of magnesium oxide in spite of the less covalent character of the bonds within the molecule.
